See /sys/dev/usb/quirk/usb_quirk.h or run "usbconfig dump_quirk_names"
for the complete list of supported quirks.
LOADER TUNABLE
The following tunable can be set at the loader(8) prompt before booting
the kernel, or stored in loader.conf(5).
hw.usb.quirk.%d
The value is a string whose format is:
"VendorId ProductId LowRevision HighRevision UQ_QUIRK,..."
Installs the quirks UQ_QUIRK,... for all USB devices matching
VendorId and ProductId which have a hardware revision between and
including LowRevision and HighRevision.
VendorId, ProductId, LowRevision and HighRevision are all 16 bits
numbers which can be decimal or hexadecimal based.
A maximum of 100 variables hw.usb.quirk.0, .1, ..., .99 can be
defined.
If a matching entry is found in the kernel's internal quirks
table, it is replaced by the new definition.
Else a new entry is created given that the quirk table is not
full.
The kernel iterates over the hw.usb.quirk.N variables starting at
N = 0 and stops at N = 99 or the first non-existing one.
EXAMPLES
After attaching a u3g device which appears as a USB device on ugen0.3:
usbconfig -d ugen0.3 add_quirk UQ_MSC_EJECT_WAIT
Enable a Holtec/Keep Out F85 gaming keyboard on ugen1.4:
usbconfig -d ugen1.4 add_quirk UQ_KBD_BOOTPROTO
To install a quirk at boot time, place one or several lines like the
following in loader.conf(5):
hw.usb.quirk.0="0x04d9 0xfa50 0 0xffff UQ_KBD_IGNORE"
